I live with my boyfriends family and I’m pregnant I don’t smoke but some of his family do they smoke in the porch, I don’t feel like there’s lots of smoke coming into the house but I sometimes smell it, I went for a hospital appointment the other day and the checked my carbon monoxide levels and it was a 1 is that because I’ve been breathing in 2nd hand smoke? 😥 should I be worried about this, could that level harm my baby?
